A device for determining the filling level in a container including an oscillator with two rotational oscillation elements (10, 12) of the same resonance frequency which oscillate oppositely. The oscillation elements (10, 12) are arranged coaxially, have a common rotational axis, masses of the same size, and a common mass center. Both oscillation elements (10, 12) are fixed to a common membrane which serves as a retraction spring, through which a common drive of both oscillation elements (10, 12) is possible.
